Size of wrench oil tank fittings

[peter52]

Can someone tell me the size of wrench needed for the in/out fittings on the top of the oil tank on rotax 912 uls?

Thanks

A 7/8 inch wrench fits the hose ends. Use a 3/4 inch backup wrench on the
tank top if desired, although the tank outlet requires a thin backup wrench.
